Vkiter,
While the bombas, and venoms may be very nice kites, they are not what people refer to as LEI or leading edge inflatable and do not float on the water. A lot of experienced riders are able to relaunch these kites.
HOWEVER
As a noob you will be dropping your kite a lot, you will probably have to do self rescue a couple of times in this case you would probably want a kite that would float on the water, be easy to relanch and one you could use as a flotation device in a self rescue.
The real choice you have to make is this... Bow kite vs tradicional C kite. Up until 2005 models, all kites were traditional C kites. These kites are still very nice kites with pretty good safety features. However in the 2006 models, a new bow kite has been developed. It is flatter and has a few different flying characteristics and more complicated bars. However these kites usually offer much bigger wind range (meaning you can use the same kite for much greater wind span) and offer complete depower which is a very nice safety feature.
Right now the only bow kite in production is the cabrinha crossbow but it is 1600 bucks. Windwing has their rapture comming out for I believe around 800. Other companies are also comming out with their versions.
However it will probably be another 2 months before you can have one in your hand and if you get used to a bow kite you will not really be able to fly a c shaped kite. If you start on a c you will get used to bows very quickly and learn to appreciate them.
I just started a c ouple months back. I'm still practicing and trying to master my technique. Here is what I did and what I recommend you do.
Because of Bow kites being out, C kites are extremely cheap. You can buy a used one like I did or go for a new one. Brands are mostly preference but check the reviews at
http://www.kite-surf.com to check how each kite performed.
I fly a 2004 cabrinha C02 with recon (what I believe to be an awesome safety system. But there is also 5th line safety systems and you can always get an older 4 line kite.
When looking at a kite though look at everything. Its the little things in a kite that can make it nice. For example I've seen the bags for best kites and they are small and thin. While Best kites seem to get great reviews and from having flown one I can tell you they are nice kites. I really enjoy having my cabrinha kite with its separate bar bag, backpack that extends to fit the kite with struts inflated, extra pocket for pump ETC.
